My @icloud.com is used in various browsers and devices. I tried to install updates on Mac App Store but it prompted I have the wrong password. Then I used my phone to reset the password. After resetting the password, I have no trouble signing in appleid.apple.com and icloud.com (tried and worked on various browsers). The I sign out iCloud on Mac (in System Preferences) to try signing in again. Despite typing the same password that works in the browser, I received "This action could not be completed. Try again" when signing in Mac App Store and "Verification Failed. This action could not be completed. Try again" when trying to sign in iCloud on Mac. Please help me!!!!
